康达 returns 'Solving environment: failed'

Question

我不能再使用 conda 实用程序了。多年来我经常使用它，但最近，因为我安装了 python 模块 scp（使用命令 conda install scp，我不知道它是否重要）没有任何明显的异常，我得到一旦我使用 conda（conda install …, conda update …, conda uninstall …, …，消息总是一样的）下面的错误：

Solving environment: failed

我试图查看我的 .condarc 文件，甚至删除了它，但它并没有改变 pb。你知道我可以做些什么来恢复正常工作吗？

Answer 1

降级到 conda 4.5.5 为我解决了这个问题。

并且带着咆哮的帽子：这是在大约 18 个月的 space 中第三次 conda 更新导致导致构建失败的错误，并且还有很多其他问题也。我认为它会在某个时候由核心 conda 人员修复，也许它是由第三方依赖项的特定组合引起的，但无论如何 conda 总是看起来非常错误。曾经有一个更新导致conda install conda删除了自己！

Answer 2

谢谢，成功了！以防 link 变老，这是简化的副本：

导航到 conda 信息提供的 conda 基础环境。
打开文件lib/pythonX.Y/site-packages/conda/gateways/connection/init.py。其中 X.Y 是 python 主要-次要版本。

将函数 'should_bypass_proxies_patched' 替换为：

def should_bypass_proxies_patched(should_bypass_proxies_func, url, no_proxy=None):
    if url.startswith("file://"):
        return True
    try:
        return should_bypass_proxies_func(url, no_proxy)
    except TypeError:
        return should_bypass_proxies_func(url)

Answer 3

好的。我在使用 Anaconda 3 2018 ver 时遇到了同样的问题。所以我所做的是使用 Anaconda 提示符。它会自动将基本 conda 文件链接到所需的代理。只需在提示中键入 "conda --version" 即可检查提示。然后键入 "conda install numpy"。瞧！你完成了。

Answer 4

DELETE 到 C:\Users\<YOUR_USERNAME>\.condarc，然后更新 Conda。这将在 Windows.

中解决它

conda update conda

Answer 5

我遇到了同样的问题并解决了。在 Anaconda 提示中，使用 pip install scp，而不是 conda install scp

Answer 6

我已经尝试解决这个问题一段时间了。最后我发现你应该使用 pip install 而不是 conda install。通常我们在 windows 命令提示符中使用 pip install，在 Anaconda Prompt 中使用 conda install。但对我来说，我通过在 Anaconda 提示符下使用 pip install 解决了这个问题。输出如下所示

Answer 7

我有同样的问题，我刚刚通过

解决了

1.uninstall anaconda 并下载最新版本

2.create 一个新环境并尝试在该环境中安装软件包

Answer 8

正在使用命令创建新环境

conda create --name myenv

对我有用！
